External BNC Spider Antenna Dual-Band VHF/UHF for Motorola Radios, 15m Cable, DP4 Adapter

Description

The “Spider” antenna is designed to enhance reception and transmission of portable radio signals, resulting in improved quality and range of communication. This is achieved by elevating the antenna (5-15 meters high), which increases the direct line of sight for radio communication in both reception and transmission, consequently improving signal quality. The effective operating bandwidth of the antenna is approximately 12-14 MHz.

The antenna was developed according to requirements for use by military and law enforcement structures, made with flexible elements that allow it to be folded during movement or active operations. It has proven excellent performance in field conditions during combat missions in various weather conditions, challenging terrain (elevation changes), dense forests, etc. It significantly (2-3 times) increases the radio communication range for portable radios from various manufacturers.

The antenna can be suspended at any height (building roofs, trees, poles, towers, etc.). Convenient to use when radio communication needs to be established from cover (bunkers, dugouts, trenches, basements, etc.). In this case, the antenna is deployed externally, thereby ensuring both personnel safety and reliable communication.
